Cartridge fuse for RA-6600?

SOURCE: Why does my new HP Laserjet 1020 12A cartridge print too light?

It's rare that an original HP would do that? It's more likely that it's a compatible / remanufactured cartridge. is it? Compatibles can be as good as or better than OEM (mine are for example), but there are a lot of "hacks" out there.
Either way, I would return it for a new one, because that is your problem.

*please rate me :)
